SHOE BDTTOM.

application. filed December-1e, 1925. semi No. 75,996.

This invention is designed mainly for use on shoes having leather soles when 1t 1s desired to apply to the shoe, both a sole and a of quiltedV canvas previously stitched to.

gether. t

An object of my inventlon 1s to provldea rubber sole and heel greatly increased 1n strength and durability over the rubber soles and heels already upon the market and which when attached to a shoe will not alf low the heads of the attaching nailsto pull through.- l

Another object is to firmly join a rubber sole and heel in such manner that they will not crack or break at the joining.

A Another object is to provide a novel rub- I. ber sole, or combined sole and heel which when applied to a shoe will not tend to make the wearers feet hot as is common with present day rubber soles.

A further object is to provide a rubber sole which when attached will not buckle.

A still further object is to provide a novel rubber sole or combined sole and heel which may be satisfactorily secured to the shoe bottom by nailing.

Other objects, advantages and features of invention may appear from the accompany' ing drawing, the subjoined detailed description and the appended claims.

The accompanying drawing illustrates the invention in,two of the forms in which it may be employed.

Figure l Iis a longitudinal section indicated at line w1, Fig. 2,. showing a combination rubber sole and heel.

Fig. 2 is a view on a smaller scale of the underside of the canvas reinforcing before the rubber has been applied .showing the manner of stitching together the'layers of canvas and of attaching the auxiliary heel piece.

. Fig. 3 is a like view of a separate sole reinforcement.

Fig. 4 is a longitudinal section on somewhat larger scale of the completed sole, the line of section being at as?, Fig. 3.

Fig. 5 is a section analogous to Fig. 1 showing the manner of applying a new heel after the worn heel has been cut off and removed. The greater part of the sole is broken away to contract the view.

The sole reinforcing or interlining 1 is composed preferably of two or more-layers of canvas as (1,5, c, in Figs. 1 and 2, and a, 1n Figs. 3 and 4. The several layers are joined, stiffened and strengthened by stitchings 2. A thin top facing of rubber 3 is cemented onto the canvas 1 to forma smooth surface for `the foot and a more or less thick tread of rubber 4 is cemented onto the `underside of said canvas.

A heel piece 5 constructed ofcanvas in similar manner to the piece 1 with st-iteliings. 2 is first secured by stitching the same at to the sole reinforcing 1..

, A cushion of rubber 7 is then inserted bes tween the heel piece 5 and the sole 1 and secured by nails 8.

The heel piece is narrowed at 9to allow stitchin around the edge of the sole l without sewing into the heel 5.

I do not limit myselic to the combination of the heel and sole as either may be used separately and as rubber heels applied separately have for years been used, I make no claim for such use, but the use of rubber soles as illustrated in Figs. 3 and 4, I claim 21S llfv. 4 i The sole 10 shown in said Figs. 3 and 4 1s practically the same as heretofore shown and described in Figs. 1 and 2 with-the exception that the heel is omitted; the edge 11 of the sole l0 being beveled to present a smoother edge as is common with leather soles.

To replace a worn rubber heel at 12 with a new heel,`the heel 12 may be cut oft at 13 as shown in Fig. 5 anda heel 12 of the construction shown in a former application of mine, Serial No. 2543, liled January 15, 1925, allowed September 16, 1925, may be applied and attached by thc nails 8 to the heel foun- `dation which comprises the heel piece 5,

the rubber cushion 7 and the canvas rein- 100 forcing member 1.

The sole and heel reinforcing members l and 5 are preferably more closely joined by the nails 14 which are clinched on said pieces after the cushion 7 Ahas been inserted there- 105 between.

I claim:

l, A combined sole and heel comprising a rubber tread and a facing, an intervening f reinforcement of canvas, an auxiliary heel piece of -canvas attached to said reinforce ment, and a cushion of rubber intervening between said canvas heel piece and canvas4 reinforcement'.

2. A combined sole and'heel comprising a rubber tread and a facing, an intervenlng reinforcement comprising two or more thicknesses of canvas stitched together, an auxiliary heel piece of like composition to the reinforcement, attached tol said reinforce- 10 ment; and an intervening cushion of rubher between said reinforcement and heel piece.

In testimony whereof, I have hereunto set niv hand at Los Angeles, California, this l5 7th day of' December, 1925:.
